High-pressure jet grouting pile

The high-pressure jet grouting pile comprises a pile body, a plurality of sets of fixing assemblies are arranged on the side wall of the pile body, and each fixing assembly comprises a grounding rod connected to the pile body in a sliding mode; a triggering assembly is arranged at the bottom of the pile body and is in transmission connection with the multiple sets of ground binding rods through a transmission assembly. When the pile body is installed in the base, the trigger assembly touches the ground, the multiple sets of ground binding rods are driven by the trigger assembly to slide synchronously, so that the ground binding rods are inserted into the base, and the pile body is fixed. When the pile body is installed in a base, the triggering assembly touches the ground, the multiple sets of ground binding rods are driven by the triggering assembly to slide synchronously, the ground binding rods are inserted into the base, the pile body is fixed, and therefore when the pile body is installed in the base, th
